4. Most Important Port In
Motherboard
•Keyboard and mouse port
•Parallel port and serial port
•Processor socket
•AGP slot
•PCI slot
•CMOS Battery
•ISA Slot
•Date and connector
•Memory Slot
•Floppy Port
•Fan Header
•Main Power Connecter

5. •KEYBOARD AND MOUSE PORT
This port connected to motherboard
which work is an input device of
computer. This port called are PS2 Port.

6. This port can used for scanners and printers.This port also
